Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

One of the more common issues besides the brake switch on this model is the shifter itself.It houses electronics that allow shifting out of park and these electronics can fail in this shifter to where the entire shifter has to be replaced.

The first thing I would check here is to see if you have brake lights with the engine running and brake pressed.If you do most likely the shifter has failed needing replaced.

You would need to have the fault codes read out to see what codes are set in all computers as one should be set related to this fault and most likely one is set for the shifter.

Not replacing the brake wear sensors will not cause this issue here.

Is it coming out of park now at all to drive it?

Customer: replied 3 months ago.
I just push a pen behind a hole behind shifter it pushes something that takes it right out of gear and then it shifts fine

O.k.,that is the manual release.

I dont see this as the vehicle needing driven for a long period of time to reset this fault unless you still have low voltage but usually this isnt the case if the engine starts up.

It does sound like they may have replaced the electronics/shifter when the drink was spilled but there is a chance it has failed again needing replaced as this is most common and may need the same part replaced again that they had replaced when the drink spilled.

It would be best to have the vehicle scanned for any fault codes.This way if any codes are set this will help with diagnosing and locating the fault here.This needs done with either a dealers sds machine or a compatible scan tool that can plug in and communicate with all computers.I do suspect the shifter is the cause here again.

Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.Your 5 star rating is appreciated

Thanks Pete
